Performing numerous tightening operations within one day can lead to operators’ fatigue. Among the many responsible factors we can find:

• the strength in supporting the tool;
• the force used to perform the action.

A valid help in these situations is offered by ergonomic aids, which as a more obvious advantage eliminate the force in supporting the tool as well as allowing to maintain a good wrist position and perpendicularity at the working point.

For manufacturing companies training is a fundamental aspect for the growth and development of skills in design and production. And to interface with an interlocutor who is also competent in training – and therefore is capable of making his know-how available – represents a great competitive advantage, as well as being distinctive.

More and more in production lines the components to be assembled contemplate numerous variants which imply, in turn, the use of different types of screws; the manual workstations managed by operators therefore require extreme production flexibility as well as fundamental precautions to reduce fatigue not only physical but also mental due to the continuous monitoring of the operations to be performed.
